SPECIFICATION forming part of Letters Patent No. 727,888, dated May 12,1903.

Application filed July 14, 1902.

To all whom it may concern:

Be it knownt-hatl, BOSE B. BOWERS, a citizen of the United States,residing at Macon, in the county of Bibb and State of Georgia, haveinvented certain new and useful Improvements in Weight Stop-Motions forSpindles; and I do hereby declare the following to be a full, clear, andexactdescription of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to. new and useful improvements in weight stop-motions adapted for use in twine-winding spindles; and it consists in aframe with a tilting lever mounted thereon having a slotted end, averticallyadjustable block mounted on the lever, aneccentrically-journaled weighted wheel carried by the block, andspring-actuated mechanism for stopping the rotary movement of thewinding-spindle. a

The invention consists, further, in Variou details of construction andcombinations of parts, as will be hereinafter more fully described, andthen specifically defined in the appended claims.

My invention is clearly illustrated in the accompanying drawings, which,with the let ters of reference marked thereon, form a part of thisapplication, and in which drawings similar letters of reference indicatelike parts in the several views, in which Figure l is a side elevationof my improved' mechanism for stopping a winding-spindle. Fig. 2 isacross-sectional view looking in the direction of the arrow in Fig. 1.Fig. 3 is a top plan view. Fig. 4 is a detail View showingthespring-actuated mechanism for re-' leasing the lever carrying theweighted wheel. Fig. 5 is a cross-sectional View through the weightedwheel and angle-lever supporting the same. v

Reference now being had to the details of the drawings by letter, Adesignates a frame, in which a shaft B is journaled, on which twine isto be wound on a suitable spool or spindle rotating with said shaft.

0 designates a stub-shaft which is carried on the upright C, forming aportion of the frame of the device, and pivotally mounted on saidstub-shaft is alever D, which may be of any suitable shape found bestadapted for Serial No. 115,494. (No model.)

'whichsaidjslot islocated is channeled-out to receive a plate E,whichlcarries a bolt F,

passing through said slot and projecting laterally from the face of theleversufliciently to form a bearing for an eccentrically-jour- .naledWheel G,having ,a.weighted portion G. ,A second bolt H, which isfastened to said plate, passes through the. slot D', and by means of asuitable nut and washer ou -the threaded end thereof it will be"observed that the plate, and also the wheel carried thereby, mayberaised or lowered for a purpose-which will hereinafter appear. Saidlever D is of such a length that the weighted wheel G when mounted asdescribed will be positioned directly above the spindle, so that as thetwine winds upon the spindle and when it increases in diameter it willcontact with the lowest portion of said wheel, and by reason of thefrictional contact between the weighted wheel and the twine-winding saidwheel will be caused to rotate, and being concentrically journaled thelever carrying the wheel will be caused to .tilt.

Mounted in an upright M of the standard is aycylindrical shell or boxingO, which is notched, as at O, and in the bore of said casing' is mounteda sliding rod P, which is notch'ed at'P, which latter notch when in oneposition will register with the notch O.

A diskwheel Q is keyed to one end of said rod P, whereby the operatormay pull upon said rod, which is spring-actuated by a spring T,

hereinafter described, for the purpose of bringing the notch in said rodinto registration with the notch 0 when it is desired to adjust the freeend of the lever D in said notches in readiness for operation instopping the winding-spindle. of the rod 1? is a bar 'R,,to. which barasecond rod or arm S is fastened, which in the present instance is shownas parallel withthe rod P and spaced apart therefrom a suitabledistance. A spring Tis'fastened at one end of said upright M, and itsfree end is designed to be held yieldingly against said rod S for thepurpose of normally holding said arm or rod and bar R at their farthestlimits from the upright M. Keyed to the rod Pisa bar T, the

Fastened to one end lower end of which is forked and is provided as abelt-shifting device. On the shaft W is a pulley which has beltedconnection with a pulley W on the shaft carrying the spindle, and Vdesignates an idler onto which the belt may be shifted by the belt-shifting arm when it is desired to start and stop the mechanism.

The operation of my weight stop-motion for winding twine on spindles isas follows The operator first pulls upon the hand-wheel Q, causing thetwo notches in the casing O and rod P to come into registration, and thefree end of the lever is inserted in said notches. When thus held, itwill be observed that the rod P is acted upon by the tension of thespring, which has a normal tendency to hold the notches out ofregistration. \Vhen the lever has been thus adjusted, the beltshiftingarm holds the belt upon the pulley on shaft W, which through itsconnections with the spindle will cause the latter to rotate and windthe twine. By reason of the wheel G being weighted about a portion ofits circumference such weighted part would by gravity normally restadjacent to the winding-spindle. As the twine being wound increases insize and comes in contact with the circumference of said wheel thefrictional contact between the wheel and the twine will cause the wheelto rotate, and being eccentrioally journaled the lever ,D will be causedto tilt, and the free end thereof will draw down out of the registeringnotches in said casing and rod P, and the spring which bears against thearm or rod S will throw the rod P away from the lever, and thebelt-shifting arm will throw the belt off the pulley onto the idler andthe spindle will stop. As the twine is removed the weighted wheel willassume its normal position with the weighted portion down, and as soonas the operator resets the free end of the lever in the registeringnotches, said notches being brought into registration by pulling out therod P, the belt is again shifted, and the mechanism will be put inmotion and a new twine will be wound.

It will be observed that by the provision of the elongated slot in thelever the weighted cam-wheel may be raised or lowered for the purpose ofgaging the size of the winding of twine.

Having thus described my 1nvention,what I claim to be new, and desire tosecure by Letters Patent, is-

1. A stop mechanism for winding-spindles, consisting of a frame, atilting lever mounted thereon, having a slotted end, averticallyadjustable block mounted on said lever, a stub-shaft carriedby said block, an eccentrio-ally journaled weighted wheel on saidstub-shaft, a spring-actuated rod having a notch therein, a notchedcasing in which said rod is mounted to have a longitudinal movement, thefree end of said lever designed to engage in said notches when they arebrought into registration, and belt-shifting mechanism actuated by saidrod as the lever is released from said notches, as set forth.

2. Astop mechanism for winding-machines, comprising a frame, a spindlemounted therein, a lever having a tilting motion, aneccentrically-mounted weighted wheel journaled on said lever, a hollowcasing having a notch in its circumference, a rod mounted in said casingand having a notch therein which is adapted to be brought intoregistration with the notch in said casing, the free end of said leveradapted to engage said notches when in registration, a bar fastened tosaid rod, an arm or rod secured to the other end of said bar, a springbearing against said arm, and a belt-shifting bar keyed to said notchedrod, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

BOSE B. BOWERS.
